Soak the cashews in water for 8 hours. Drain, reserving the soaking water. While cashews are soaking, cover chipotle pepper in 1 cup of warm water.
Put soaked cashews and 2 cups of the soaking water in a blender and blend until creamy.
Add soaked chipotle pepper, chopped bell peppers, miso, 1½ teaspoons salt, lemon juice, nutritional yeast, regular and smoked paprika, onion powder, garlic powder and white pepper. Blend until silky smooth.
Add the tomatoes and 2 more cups of water and blend again until smooth, about 20 seconds. Do not over-blend or the mixture will become frothy. Add additional water, if needed, to achieve the desired consistency. The soup should be creamy, like sour cream, but not overly thick.
Add salt, if needed. Top each serving with an optional dollop of Cashew Yogurt*.
Blend the cashews, water and probiotic powder in a high-performance blender, adding more water if necessary to achieve a smooth, creamy texture.
Put the cashew cream in a jar and place it in a warm (not hot) location to ferment for 8–12 hours. (Less fermentation time is required in warmer weather.)
Once the yogurt has fermented to suit your tastes, stir in as much lemon juice as you like to give it the amount of tartness you want.
Yogurt may be stored in a sealed glass container in the refrigerator for up to 1 week.
